Application filed October 31,1905. Serial No. 285,336.

To all whom it may concern:

Be it known that'I, OWEN W. WrrTMER, a citizen of the United States,residing at C0- lumbus, in the county of Franklin and State of Ohio,have invented aP-inew and useful Brake-Lever Fulcrum, of which thefollowing is a specification.

The principal object of the present invention is to provide a simpleform of a brake-lever fulcrum which may be attached to a brake-beam andadjusted to any desired po.

sition as required by the angle of the brakelever, so that separatecastings for each brakelever angle are rendered unnecessary.

A further object of the invention is to provide a brake lever fulcrum ofsimple construction which maybe readily applied to standard beams andwhich when once adjusted to the required angle may be firmly locked inposition by its attaching means.

With these and other objects in view, as will more fully hereinafterappear, the invention consists in certain novel features of constructionand arrangement ofparts hereinafter fully described, illustrated in theaccompanying drawings, and particularly pointed out in the appendedclaims, it being understood that various changes in the form,proportions, size, and minor details of the structure may be madewithout departing from the spirit or sacrificing any of the advantagesof the invention. 1

In the accompanying drawings, Figure 1 is a plan view of a brake-leverfulcrum constructed in accordance with the invention,

the viewshowing a portion of a standard brake-beam. Fig. 2 is a sideelevation of the same, partly in section, the brake-beam being alsoshown in section. Fig. 3 is a detached perspective view of thebrake-lever fulcrumdetached. Fig. 4 is a similar view of thefulcrum-clamping ring.

Similar numeralsof reference are employed to indicate correspondingparts throughout the form of a disk 10, that is formed integralwith apair of pivot ears or lugs 11, provided with openings 12 for the passageof the pin by which the brake-lever is connected, and the structure isstrengthened by suitable ribs 13. Over the disk 10is placed aclamping-ring 14, having at its inner face a groove 15 of such diameteras to permit free turning of the fulcrum member until the ears arepresented at the angle required by the brake-lever. Pro jecting from therear face of the ring are two ears 16, that are arranged to engage overthe opposite edges of the forward flange of the brake-beam, and theseears, together with the lugs 17, projecting from the ring proper,

- are provided with openings 18 for the passage of securing members inthe form of rivets or bolts, said rivets or bolts extending also throughopenings formed in the flange of-the brake-beam.

The device forming the subject'of the present invention may be attachedat any point in the length of the beam, it being merely necessary tofirst place the fulcrum member in position within the ring and then turnthe ring and fulcrum member until the ears l6 fit over the oppositeedges of the flange, care being taken that the fulcrum memberis adjustedto the required angle. The disk 10 will then be clamped between theflange of the brake-beam and the ring 14 and will beheld from rotativemovement. The securing bolts or rivets are-then placed in position, andthe fulcrum is ready for use;

With a fulcrum constructed in accordance with the present invention itis unnecessary to make special castings for each angle of thebrake-lever, thus doing away with rights and lefts, and may be appliedat any desired point. without the removal of the brake-shoes, so thatrepairs may be quickly made in case of accidental breakage.

Having thus described the invention, what is claimed is 1. A brake-leverfulcrum having pivotears and a base member, and a clampingring having acircular recess for the reception of said base and provided withinclined brakebeam-engaging lugs facing, respectively, in oppositedirections to permit their engagement with the beam by circumferentialadjustment of the ring.

2. A brake-beam fulcrum having pivotlugs and a base member, and a.clampingring having a recess to receive said base member, saidclamping-rin being provided with brake-beam-engaging, ugs arranged atdiametrically opposite points and facing, respectively, in-oppositedirections to permit their engagement with the beam by circumferen- Intestimony that I claim the foregoing as my own I have hereto aflixed mysignature in the presence of two witnesses.
